MC9S12C32 - interrupt table

randy_s_woods — Wed, 21 Mar 2007 01:33:00 GMT

I am attempting to setup the port p interrupt on a MC9S12C32 process (NanoCore from technological arts) as shown below. I am trying to use the interrupt to read in a 1 Hz signal from a Real Time Clock therefore, I set Port P up as an input and enabled the interrupt inside the PIEP register (although just to write the declaration I should not even need to do this).

interrupt 56 void 1Hz_handler(void) // port P5
// ENABLED:
// PURPOSE:
{

}

I keep getting an error stating that this is an invalid number. I have counted up in the vector table several times and I keep getting Vportp to be 56. Has anybody used the port p vectors?

Just a little more clarification. When I looked in the Device user guide (MC9S12C32) it shows up as interrupt 37 when the reserved interrupts are removed from the counting. I attempted to use 37 as the interrpt and this gives the same error "C2704: Illegal number". When I looked at the code warrior file mc9s12c32.inc the interrupt would be 57.

Woops! 1Hz_handler is not a valid name.....
